Chapter 3.3: Research Methods

Question 1

The first demonstration that a brain area controlled a particular aspect of behavior pertained to which type of behavior?

Answer 1

Language

Question 2

Which of the following is a method to inactive a brain area temporarily?

Answer 2

Transcranial magnetic stimulation

Question 3

What does the ontogenetic technique enable researchers to test?

Answer 3

The functions of a particular type of neuron

Question 4

EEG and MEG are advantageous for measuring which of the following?

Answer 4

Changes in brain activity over very short periods of time

Question 5

Which of these is the first step for positron-emission tomography (PET)?

Answer 5

Inject a radioactive chemical into the blood

Question 6

What is one advantage of fMRI over PET scans?

Answer 6

The fMRI technique does not expose the brain to radioactivity

Question 7

Comparing MRI and fMRI, which one(s) measure the response of brain chemicals to a magnetic field? Which one(s) show which brain areas are most active at the moment?

Answer 7

Both measure responses of brain chemicals to a magnetic field. Only fMRI shoes which brains areas are most active at the moment

Question 8

Why should we be cautious when interpreting many of the reports linking certain aspects of brain anatomy to behavior?

Answer 8

Many published studies were based on small samples.
